| Abstract/Contents: | "Tenacity™, comprised of the active ingredient mesotrione, is a new active ingredient for the turfgrass market. The structure of mesotrione is based on leptospermone, a naturally occurring compound with allelopathic activity which was found around the bottlebrush plant (Callistemon citrinus). Mesotrione belongs to the triketone herbicide family, and the mode of action belongs with the HPPD inhibitors (p-hydroxyphenylpyruvate dioxygenase) which blocks formation of plastoquinone and subsequent carotenoid production. The typical symptom observed from a Tenacity™ application is bleaching, followed by necrosis and plant death. Tenacity™ is safe when applied to cool season grasses such as Kentucky bluegrass and tall fescue. Application rates up to 8 fl oz pr/A are allowed on these species. On perennial ryegrass and fine fescues a maximum rate of 5 fl oz pr/A is allowed. Tenacity™ has both foliar and soil activity. Sixteen (16) fl oz pr/A/year is the maximum application, so users will need to plan their treatments according to what they hope to accomplish, and keep in mind that a sequential application 3 weeks after the initial treatment will be required. The weed spectrum is varied, as Tenacity™ has both pre-emergence and post-emergence activity, and is active on grassy weed species, broadleaves and nutsedge. Nimblewill control is excellent with Tenacity™, and a unique fit for the turf markets. Pre-emergence nutsedge activity is also unique. Tenacity™ will also selectively remove bentgrass from cool season turf species such as bluegrass and fescues; three applications of 4 oz pr/A are required, at 2-3 week intervals, to effectively remove the bentgrass competition. The most unique characteristic of Tenacity™ is the ability to prevent weed competition when applied at seeding. No reduction in turf stand or interference with emergence has been observed in 3-years of te sting. Improved stands and turf quality have been obtained due to removal of the weed competition. Seeding can be accomplished in spring, early summer or fall." |
